        <footnote id="F1">On May 24, 2017, the reporting person was granted financial-based performance share units that would be measured over a three year time period. The payout could be increased to 200% of target or reduced to 0% based on achievement of the key metrics. The performance share units have been accumulating quarterly dividend equivalents. Based on company performance over the three period ending on December 31, 2019, the Compensation Committee certified on February 18, 2020 that the reporting person was entitled to 59% of her target opportunity.</footnote>
